摘要

初步分析了三根单芯电缆线的几何结构对产生磁场的影响。本文采用数值和实验方法来估计由导电或磁性材料制成的开式或闭式屏蔽的性能。提出了一种新型高压单芯“绿色电缆”，其铝导体由铜线和铁磁护套实现的双层屏蔽层卷绕而成。

Shielding techniques of the low-frequency magnetic field from cable power lines

The influence of the geometrical configuration of three single-core cable lines on the generated magnetic field is evaluated in the preliminary analysis. Numerical and experimental procedures are applied to estimate the performances of open or closed shields made of conductive or magnetic materials. A new high-voltage single-core "green cable" is proposed, in which the aluminum conductor is coiled by a double-layer shield realized with copper wires and a ferromagnetic sheath.
